Pulses power to shorted and overloaded circuits (patented Pulsar® technology)

A portable trailer tester for the Mobile and Commercial Trailer Repair Technician, the Smart MUTT® places a load on the trailer’s electrical circuits to identify wiring problems while providing remote control operation lights. Built to facilitate a one-man testing operation, the Smart MUTT® reduces guesswork and inspection time to prevent failures that lead to expensive road calls and citations. The Smart MUTT® requires an internal battery or external power source for operation. The internal battery can be purchased separately or directly from a battery distributor. For use on 7-way Round Pin Trailer Connections.
